Comparison of transanal specimen extraction (TSE) and transabdominal specimen extraction (TASE) in laparoscopic rectal surgery is still sparsely reported. Trauma, pain, scarring, and bad psychological suggestion have long been considered an inevitable outcome of surgery. For laparoscopic rectal cancer surgery, whether TSE or TASE is beneficial in terms of technical platforms, indications, contraindications, technical requirements for aseptic operation, tumor-free operation, prevention and treatment of complications still has not reached a unified consensus and standards. Recently, comparison of TSE and TASE in laparoscopic rectal surgery has still been sparsely reported.

In this study, we retrospectively analyzed the short-term outcomes of TSE and TASE in laparoscopic rectal surgery in a single institution in southern China.

Material and methods
Patients who underwent laparoscopic radical rectal cancer surgery using either TSE or TASE were recruited. Data, including patient demographics, perioperative and postoperative variables, were analyzed retrospectively.

Sixty-seven patients were included in this study. Thirty patients underwent TSE and 37 patients underwent TASE. The two groups were similar in demographics and tumor characteristics. Postoperative complications were similar in both groups, except that wound infection was lower for the TSE group (p = 0.122). The TSE group had a better cosmetic result with no abdominal incision and no differences in circumferential margins, distal resection margins or completeness of total mesorectal excision.

Laparoscopic TSE is recommended in the treatment of rectal cancer with similar oncologic outcomes compared with conventional TASE. It is mini-invasive surgery and has the advantage of better cosmetic results. There is a need for further randomized studies to refine the applicability of laparoscopic TSE in rectal cancer.
